Application filed April 22, 1912; Serial No. 692,239.

To all whom it may concern:

Be it known that I, JAMns F. CRAVEN, a resident of Pittsburgh, in thecounty! of Allegheny and State of Pennsylvania, ave invented a new anduseful Improvement in Rece tacles for Containing and Dischargingsemisolid and Pasty Substances, of whic the following is aspecification.

This invention relates to receptacles for containing, storing,transporting and discharging semi-solid and pasty substances, such asgreases or lubricants, vaseline, cold cream, butter, lard, printers rother inks, paints and like substances, and delivering the same from thecontainer in any desire of any desired shape or size constructed fromany desired material. It

, but is shown as I for a purpose to be quantity "or quantities. "1.1;;

The invention isan improvement upon that shown, described and claimed inmy Patent No. 993,511 granted May 30th, 1911,

for a device of the character described.

The particular object of the present invention is to provide an improvedconstruc tion in such a contents from the receptacle and which may beoperated to close the outlet orifice when the operation of dischargingthe contents ceases. I

The invention comprises the construction and arran ement of partshereinafter demay be made of glass, paper or paste board formed of asubstantially cylindrical tube 1 of thin sheet metal. One end of thetube is headed outwardly, as at 2, described, and the other end isstraight or smooth, as shown. The beaded end of the receptacle is closedby. means of a thin sheet metal head or cap 3 provided with a dischargeorifice 4, and may device for discharging the be removable to permitfilling the receptacle, but is shown .as crim ed around the bead 2 onthe end of the tu e. the receptacle is closed by means of a cup shapedsleeve or head 5. I

In order'to force the semi-solid or pasty substance out of thereceptacle, there is provided a piston or.follower 6 which may be formedof wood, metal or like material and is shown formed as a solid body-ofcork having a square or otherwise suitably shaped nut 7 seated in asocket therein and provided with a threaded bore. The piston or follower6 is adapted to be moved longitudinally in the tubular receptacle andwhen so moved forces the material out through the discharge orifice 4.Any suitable means for moving the piston may be employed, that showncomprisinga threaded rod or screw 8 arrangedcentrally in the receptacleand extending from end to end thereof and through a threaded bore in thepiston 6. The threaded rod or shaft 8, the threads of which arepreferably double and left handed, is secured to the end closure orsleeve 5, which forms a handle member for rotating the rod or shaft whendesired. Suitable means is provided for preventing rotationof the pistonor follower '6 as it movesendwise through the container, as, forexample, a longitudinal rib 9 on the inner face of the'tube 1 whichengages a groove in the piston. In the case of the sheet metal tubeshown, the usual crimped seam of the tube forms a sufiicient rib forthis purpose, as illustrated. y In some cases the rib 9 may the interiorsurface of the tube left perfectly smooth, as when the device is made ofglass, in which case the follower is formedtofit the interior wall ofthe tube sufficiently close and tight so that the friction between thefollower and tube, supplementing the resistance to rotation offered bythe contents of the receptacle, the follower. Consequently, of the endcap or closure 5, the threaded rod or shaft 8 rotates therewith andmoves the piston longitudinally through the container to discharge itscontents therefrom.

The other end ofwill prevent rotation of upon rotation At its forwardend, the rod or shaft 8 is provided with an enlargement or head 10formed plished by a sim 1e spinning operation. The enlargement or ead10- is in line with the discharge orifice 4 and is arranged to close isslightly thicker than the end cap 3, and

atits central portion'is bent to form a nut provided with threads 20fitting the threaded rod or shaft 8. Preferably, and as shown, thethreads are formed in the inner surface of the member, which at itscenter is somewhat conical, so that the threads gradually disappear, asat 21, Fig. 5, on the side of the member away from the dischargeorifice. Preferably about two full threads are formed in the member 11.The member 11 is slightly cupped outwardly, as shown, and its peripheryis beaded or otherwise shaped to form a flange 12, which rests upon thehead 2 at the end of the receptacle 1. Adjacent to the enlargement orhead 10 on the end of the rod or shaft, the threads thereof are strippedfrom the rod or shaft to provide a short, smooth, cylindrical portion13.ThlS portion of the shaft is preferably of very slightly greater lengththan thelength of the threaded portionof the member 11.

The rod or shaft 8 is made of such length and the end closure or cap 5is so formed and attached thereto that when the head 10 of the rod orshaft engages the cap 3 and closes the orifice 4, only a very slightspace, if any, intervenes between the cap 5 and the end of the tube 1.

When the receptacle is filled, the piston 6 lies againstcap 5 and thehead-1O on the screw rod 8 is in contact with the cap 3 and closes theorifice 4, the parts being in the position shown in Fig. 1. To dischargethe contents, the rod or shaft 8 is rotated by turning .the cap 5, theperiphery of which 'is knurled, as at 14, thereby causing the piston 6to travel toward the discharge end of the tube. The. rotation of the rod8 in the proper direction to cause the forward travel of the piston hasthe effect of unscrewing the threaded rod or shaft 8 from themember 11,until .the threads on the rod or sha t have been withdrawn there from,and the smooth, reduced, unthreaded portion 13 of the rod or shaftbrought within the threads 20 inthe member 11. In this position of theparts, the head or"enlargement 10 rests against the forward end of themember, as-shown in Fig. 5. Further rotation of the end cap in theproper direction continues to discharge the contents of the receptaclefrom its discharge orifice as desired. When a sufiicient portion of thecontents of the receptacle has been discharged, the end .cap 5 isrotated in the reverse direction.- This causes the threads at the end ofthe rod or shaft 8 to engage the threads 20 of thenut 11, the incompletethreads 21 assisting this engagement, when rotation of the cap moves therod or shaft 8 forwardly until the enlargement 10 closes the dischargeorifice 4.

In most cases, the form of head illustrated in Fig. 1 will serve allpurposes, as the device is primarily intended to be cheaply constructedand to contain comparatively inexpensive products. Under somecircumstances, however, the receptacle may be used to contain eitherexpensive products, of which none should be wasted, or products whichharden if exposed to the air, as, printers inks. For such devices, Ipnefer to employ the form of head or enlargement shown in Fig. 2, andwhich is provided with a knob 'or protuberance 15 to fit the opening ordischarge orifice 4. The operation of this form of the device is thesame as that shown in Fig. 1. When the end cap 5 is first rotated in theproper direction, it withdraws the knob -or protuberance 15 from theorifice 4 and opens the same to permit discharge of the contents fromthe receptacle. When the end cap is rotated in the reverse direction,the enlargement or head 10 moves forwardly as before and the knob orprotuberance 15 is moved into and fills the discharge orifice 4, itsouter surface being formed tobe flush with the outer surface of the endcap 3. This device consequently presents an attractive appearance fromthe outside. The operation of closing the orifice 4 always clears it'ofany of the contents of the receptacle which might be contained therein,if the protuberance 15 were omitted. This prevents the liability ofprinters ink or like substances contained in the receptacle fromhardening and closing the discharge orifice.

In the use of the device, the grease, cosmetics, ink, or other materialis filled into the receptacle at the factory and the'receptacle is thenclosed, and can be packed, shipped and stored in a practically sealed.condition. The filling is done before the cap-5 isplaced in position.This is accomplished in the following manner: The member 11 is placed onthe rod or shaft 8 and the head or enlargement 10 is then spun orotherwise upset on the rod or shaft by the use of any I suitable tool ormachine. The member 11' is then placed in position with its'flange 12over the head 2 on the tube 1, aft'er'which the end cap or closure 3 isplaced over the end of the tube and its periphery beaded,

crimped or bent around the bead 2 on the end of. the tube 1, as at 16.The bead 16 is then squeezed or pressed together to secure ton havingits end like.

the cap to the tube and pinch the flange 12 of the member 11 in thejoint, thus forming a tight connection between these three members. Thetube is then filled with the grease, cosmetic, ink or other substancewhich it is intended to contain and the piston 6 is screwed onto the rodor shaft 8. The, end cap 5 is then placed in position over the end ofthe tube and secured to the rod or shaft 8.

The end cap 5 may be formed in any preferred manner and secured to therod or shaft 8 asdesired. Fig. 1 illustrates the end cap 5 as formedwith a slight central depression 17 and with a central aperture throughwhich a reduced end portion 18 of the rod or shaft 8 projects. Thereduced end 18 of the rod or shaft is headed or spun over, as at 19, toform a head contained within the depression 17 and rigidly securing theend cap 5 to rotate with the rod or shaft. The head 19 may be formed inthe same manner and by the sameoperations as the head 10.

It will be observed that with the form of the device described, thereceptacle is non-re fillable. In other words, after having once beenfilled, it cannot be refilled without deforming or destroying thereceptacle. Under some circumstances it is desirable to close the recetacle in a manner to permit of its being refil ed as, for example, inreceptacles made for gift purposes and of expensive material which, ifdesired, may be of sheet metal plated with silver, gold or the In thiscase, the rod or shaft 8 is formed with a threaded bore 22 on its endand the cap 5, as illustrated in Fig. 2, is secured to the end cap 5 bymeans of a screw 23 threaded through the end cap and to the bore 22.With this form of the invention, when the receptacle is emptied, thepiston may be returned to the cap 5 removed. The piston is then re movedfrom the rod or shaft 8. The receptacle may then be again filled, thepiston again screwed on the rod or shaft, andthe cap 5 screwed to therod or shaft with the screw 23, as before described.
